Hi all,
I am facing problem on printer XC-640 the toll carriage its not going down after print to cut . But the tool carriage move to position and read the crop mark .
I changed the cable but its not moving down .
What i have to do solve this issue ?

I got mine from Digiprint Supplies. If you have an XR-640 too their part # is PCBRO12305. If you have a different printer it'll need another cable but you'll be able to find the correct one on the DP website.

You may want to replace or carefully clean the clear cable guide too (DP part # PMERO15783 for the XR-640) as apparently a common cause of the flat cable failing is a buildup of ink/dirt on the cable guide.

Greeting to all from the Caribbean Trinidad . Researching online to find a video on how to carry out the above change on the XR-640 but no luck .
Can anyone point me in the direction to find a video or literature on how to change the cut carriage cable-card for the roland XR 640
